Windows 7 OEM System Locked Preinstallation Activation

Code of Authenticity (CoA) and Windows (OEM) Sticker

Systems manufactured before 2012 were sold with a Windows 7 CoA. This contained the Edition of Windows 7 and a 25 Digit Product Key.

Systems sold after 2012 have the following sticker to identify that they have a Windows OEM License.

What is OEM System Locked Preinstallation?

Original Equipment Manufacturers like Dell preinstall Windows on millions of Devices. In order to avoid having to manually type an alpha-numeric 25 digit product key and calling Microsoft for Product Activation on every single computer they manufacture they activate their devices using a different mechanism called OEM System Locked Preinstallation (OEM SLP).

MSDM – Microsoft Digital Marker

For systems sold with Windows 8 OEM and Windows 10 OEM the 25 digit product key is not seen printed on a label but is embedded in the MSDM table of the UEFI BIOS. Windows 10 Installation Media downloadable from Microsoft will automatically input these product keys during installation and as it’s multi-edition it will automatically select the correct Edition corresponding to the Windows Product Key. Although most people shouldn’t need to, one can check if they have a MSDM by installing RWEverything. The ACPI tables should load by default (if not select Access → ACPI Tables).

SLIC – System License Internal Code

For Windows 7, the 25 digit product key was printed on a CoA but it is typically not used during Windows 7 Installation. Instead Windows 7 is activated from Factory using OEM System Locked Preinstallation. For Windows 7 OEM SLP three things are required:

  • The System has a SLIC Version of 2.1
  • The Installation Media Inputs:
    • A xrm-ms File.
    • A Generic OEM SLP Key (Generic for the OEM e.g. Dell and the Edition of Windows 7 e.g. Professional).

If all three requirements are satisfied OEM SLP is applied. Although most people shouldn’t need to, one can check if they have a SLIC by installing RWEverything. The ACPI tables should load by default (if not select Access → ACPI Tables).

A SLIC Version of 1.0 is for Windows XP, a SLIC Version of 2.0 is for Windows Vista and a SLIC Version of 2.1 is for Windows 7. Systems shipped with Windows 8.1 Pro and Windows 10 Pro will have a SLIC Version of 2.1 in addition to the MDSM because they are eligible for OEM Downgrade Rights to Windows 7 Pro OEM.

Installation Media

  • Windows 10 (Version 1511 and Later)
    • Accepts Windows 10 MSDM
    • Accepts Windows 8.1 MSDM and Windows 8 MSDM
    • Accepts Windows 7 CoA Key
      • One Time Activation Use
      • System Motherboard Hardware Profile Registered with a Microsoft Product Activation Server No Key Required for Reinstall
    • Does Not Activate from a Clean Install using the SLIC
      • Upgrade Install from SLIC Works
      • Genuine Ticket Generated on Windows 7 Activated SLIC Works
  • Windows 7 OEM Media
    • Major OEM Media e.g. Dell Activates Using the OEM SLP
      • Has a sources\$OEM$\$$\system32\OEM folder which contains the OEM.xrm-ms file.
      • Has a sources\$OEM$\$$\setup\scripts folder which contains an OOBE script and SLP script.

The Out of the Box Experience (OOBE) script calls the System Locked Preinstallation Script (SLP) script. The SLP script has two lines the first line installs the OEM.xrm-ms file and the second line inputs the generic OEM SLP key. This is the key for Dell Windows 7 Professional.

This is the SLP script from a Dell unmodified Dell Windows 7 Professional Reinstallation ISO:

Windows 7 Retail Media or System Builder OEM Media does not contain an $OEM$ folder and will not apply OEM SLP and will instead ask for a Retail Product Key During Installation. This has caused a lot of confusion regarding OEM SLP.

Applying Windows 7 OEM SLP Using Retail Media

Retail Installation Media asks for a Product Key During Installation. We can uncheck “Automatically Activate Windows when I’m Online”.

Post Installation we can apply the OEM System Locked Preinstallation. Download the following:

Extract, select your OEM and then Edition of Windows 7. Copy the OEM folder directly to the C:\Drive. Right click the SLP.cmd file and select run as administrator, this will apply OEM SLP as per the factory settings.

The slp.cmd script for Dell Windows 7 Professional is shown below. Note the OEM folder must be copied to the C:\ Drive directly so the script can find the OEM.xrm-ms file.

OEM SLP Key Collection – For Information Only

Many people on forums are instructed to use key finders to find their OEM Product Key and instead will find the OEM SLP key and fail to activate using it. These keys will only activate using OEM SLP, they do not activate using the activation methods of Retail Product Keys.

Note the first 5 digits of the Product ID listed below will differ corresponding to the language installed.
